Cover structure, manufacturing method thereof and display device
The present disclosure discloses a cover structure, a manufacturing method thereof and a display device. The cover structure includes a first and a second transparent flexible film layer, a glass panel, and a first optical adhesive layer. The first transparent flexible film layer has a folded region and a non-folded region. The glass panel is disposed on the first transparent flexible film layer, and a projection of the glass panel on the first transparent flexible film layer is located inside the non-folded region. A part of the first optical adhesive layer is formed at a side of the glass panel facing away from the first transparent flexible film layer, and a part of the first optical adhesive layer covers the folded region of the first transparent flexible film layer. The second transparent flexible film layer is formed at a side of the first optical adhesive layer facing away from the first transparent flexible film layer.
1. A cover structure, comprising:
a first transparent flexible film layer having a folded region and a non-folded region;
a glass panel directly contacts a side of the first transparent flexible film layer, wherein a projection of the glass panel on a side of the first transparent flexible film layer is located inside the non-folded region and the folded region of the first transparent flexible film layer is not provided with the glass panel;
a first optical adhesive layer, wherein the first optical adhesive layer is a single structure, and a part of the first optical adhesive layer is formed at a side of the glass panel facing away from the first transparent flexible film layer, and a part of the first optical adhesive layer directly contacts the folded region of the first transparent flexible film layer and directly contacts side surfaces of the glass panel;
a second transparent flexible film layer formed at a side of the first optical adhesive layer facing away from the first transparent flexible film layer and directly contacts the first optical adhesive layer; and
an anti-glare layer formed at a side of the first transparent flexible film layer facing away from the second transparent flexible film layer and directly contacts the first transparent flexible film layer;
wherein the first optical adhesive layer is colorless and transparent, has a light transmittance of 90% or more;
the anti-glare layer is configured to eliminate a boundary effect between the folded region and non-folded region caused by specular reflections, thereby leading to homogenization of an optical effect of an integrated display device.
2. The cover structure according to claim 1 , wherein the glass panel is adhered to the first transparent flexible film layer.
3. The cover structure according to claim 2 , wherein an adhesive material between the glass panel and the first transparent flexible film layer is an optical adhesive.
4. The cover structure according to claim 1 , wherein material of each of the first transparent flexible film layer and the second transparent flexible film layer is polyimide.
5. A manufacturing method of a cover structure for manufacturing the cover structure according to claim 1 , wherein the manufacturing method comprises:
providing a glass panel on a non-folded region at a side of a first transparent flexible film layer;
providing a first optical adhesive layer on the glass panel, wherein the first optical adhesive layer is a single structure and a part of the first optical adhesive layer is formed at a side of the glass panel facing away from the first transparent flexible film layer, a part of the first optical adhesive layer covers a folded region of the first transparent flexible film layer and the first optical adhesive layer covers folded region of the first transparent flexible film layer;
forming a second transparent flexible film layer on the first optical adhesive layer;
creating an anti-glare particle layer on a side of the first transparent flexible film layer facing away from the second transparent flexible film layer by means of slit coating,
forming an anti-glare layer by providing a baking process for the anti-glare particle layer; and
forming a decorative ink layer on the second transparent flexible film layer by means of baking process,
wherein a side of the anti-glare layer facing away from the first transparent flexible film layer is formed with a plurality of protruding structures.
6. The manufacturing method according to claim 5 , further comprising forming a second optical adhesive layer between the first transparent flexible film layer and the glass panel.
7. A display device, wherein the display device comprises the cover structure according to claim 1 .
